We are glad to inform you about the Qt 5 porting status. Since we finished the QtCore (text mode) and QtNetwork part of Qt several months ago, we had to invest some time in supplementary libraries (such as LIBCn and LIBCx and many others) that are required by Qt and virtually all other OS/2 software we've been working on. But now we are back on track with working on the GUI part of Qt which, once done, will bring you fresh versions of many popular Qt-based GUI applications (that require Qt 5 since long time already). Among them are:
1. VirtualBox - https://en.wikipedia.org/wiki/VirtualBox
2. Scribus - https://en.wikipedia.org/wiki/Scribus
3. VLC media player - https://en.wikipedia.org/wiki/VLC_media_player
4. SMPlayer - https://en.wikipedia.org/wiki/SMPlayer
5. PSI - https://en.wikipedia.org/wiki/Psi_(instant_messaging_client)
6. Quassel - https://en.wikipedia.org/wiki/Quassel_IRC
8. QBittorent - https://en.wikipedia.org/wiki/QBittorrent
7. QPdfView - https://launchpad.net/qpdfview
9. PyQt (will bring A LOT of GUI applications) - https://en.wikipedia.org/wiki/PyQt
And, of course, besides these applications there are two Qt-based web browsers which finalizing the Qt port will bring to the OS/2 platform:
1. Falkon (former QupZilla) - https://en.wikipedia.org/wiki/Falkon
2. Otter Browser https://en.wikipedia.org/wiki/Otter_Browser
Both browsers are based on the Chromium web engine — the same one used by the Chrome browser. Our primary target is Falkon and it is what we are going to offer to the OS/2 users as an alternative to the aging OS/2 port of the Firefox browser whose development is now suspended for technical reasons.
We have an estimate to finish the GUI/Widgets part (and get the first Qt GUI application running on OS/2) in a 2 months time frame. Finishing the browser part and the rest of Qt will, of course, take longer — upto 6 months.
